The SB13PFCR25-4-COAX Coaxial Woofer from SB Acoustics represents a sophisticated solution for those seeking deep, controlled bass without compromising on space. This 150mm driver from the acclaimed PFC Paper series ingeniously integrates a full-range coaxial driver, making it an ideal choice for compact installations where every millimetre counts. Whether you are upgrading a car audio system, building a high-fidelity home theatre, or designing a bespoke multi-room setup, this unit delivers exceptional performance where traditional separate drivers simply cannot fit.

Technically, the SB13PFCR25-4-COAX is engineered for precision. With a nominal impedance of 4 ohms and a DC resistance of 3.2 ohms, it offers efficient power handling. The 44 Hz resonance frequency and 4.7 mm linear excursion (Xmax) ensure authoritative, distortion-free bass. Its low total Q factor of 0.49, combined with a sensitivity of 89 dB (1m/2.83V), allows for tight, articulate low-end reproduction. The 0.56 mH voice coil inductance and robust mechanical (Qms 2.6) and electromagnetic (Qes 0.33) damping characteristics contribute to its controlled response. The 150.5 mm diameter and 69 mm depth, with a 5 mm mounting hole diameter and four fixing points, facilitate straightforward integration into existing enclosures. This coaxial woofer is a masterclass in combining compact form with uncompromising acoustic performance.
